I've already submitted countless bug reports with plenty of details on this one and even got a reply from customer support (long time ago) basically saying "we're working on this". After at least 4-5 incremental patches (and one big dlc patch) it's still completely broken. It's the story quest that awards 1 skill point in veteran version of the dungeon.
What exactly is bugged you ask? Well... almost everything. I've tried this many, many times and here's what I've found:
- dark elf npc won't rise from the ground after the first boss (big kwama) and you can't talk to her => progress blocked, can't complete quest
- argonian npc runs off somewhere and disappears after her dialogue just before the netch boss => progress blocked, can't complete quest
- argonian npc disappears after the netch boss fight => quest objective stuck at "find dwarven engine", progress blocked, can't complete quest
- both npcs (dunmer & argonian) disappear after netch boss fight => progress blocked, can't complete quest
- argonian npc disappears after killing final boss => quest objective stuck at "return to <argonian_npc_name>", progress blocked, can't get a reward (skill point)
Few notes:
- I'm not skipping any part of the dungeon (especially monsters before the netch boss fight or the 3 alit minibosses) and all bugs listed above still happen
- I know that, for example, after final fight the argonian npc should be outside the boss room - she's not there, nor anywhere in a dungeon (and I checked it thoroughly)
- sometimes one of the "lost" npcs reappear after entering/leaving final boss room, but then quest just stucks on another objective (and it doesn't work when argonian npc gets lost after killing final boss)
- leaving dungeon, relogging, /reloadui or restarting game do not fix anything
So here it is. Few of my guildies also have this problem so it's propably nothing on my end.
I'm trying to complete this quest since 2 months and it still doesn't work. Since I sadly can't see ZOS doing anything about that, I decided to post here - maybe someone will answer.
Thanks for reading.
